This is not really how C does it.  Your wording states that using F in a
call (F(...)) is an exception to the conversion rule whilst at least
suggesting that use in function call is the only exception to the rule.

But in C, neither is the case: function designators converts to a
pointers even in call expressions, and they don't get converted when
they appear as the operand of sizeof or &.

It's not a very significant correction, but a couple of things about C
are hard to explain unless you know what the rules are.
